Whirly Birds

"We Do It Once, We Do It Right!"

  • Reduce Heat
  • Prevent Mould & Mildew
  • Replaceable Bearings
  • Easy Installation


Without ventilation, moisture condenses in roof space. Dampness is trapped.


The Windmaster Turbine Ventilator will rapidly remove hot air and moisture from your roof spaces, making your home more comfortable during the summer months and will help prevent mould and mildew. Being whisper quiet, you won't even know you have whirly birds. Made from rust resistant aluminium, your whirly bird comes in many colours to match your roof colour. The strength-ened dome is designed to resist hail damage and only precision steel bearings (patent pending) are used which can be easily replaced.


Without ventilation, heat from the laden air rise & roof space radiates into home & also limit the effective-ness of insulation.
